Subject: [PATCH] ARM: dts: samsung: exynos4210-i9100: Unconditionally enable
 LDO12

The kernel hangs for a good 12 seconds without any info being printed to
dmesg, very early in the boot process, if this regulator is not enabled.

Force-enable it to work around this issue, until we know more about the
underlying problem.
